MIPS (PIC32): branch vs. branch likely. If a branch or jump instruction is placed in the branch delay slot, the operation of both instructions is undefined. By convention, if an exception or interrupt prevents the completion of an instruction in the branch delay slot, the instruction stream is continued by re-executing the branch instruction.
